Robbie Williams has said he is not engaged to his girlfriend, despite his mother appearing to confirm the news.

Under the heading "Robbie And Ayda: Are They Or Aren't They?" on his official website, Williams simply wrote: "Hey all. We are not engaged. Rob."

Speculation began when the singer made an off-the-cuff proposal to Ayda Field on an Australian radio show.

His spokesman said it was a joke, but his mother Jan later told BBC 5Live he had been planning to pop the question.

After Williams published his denial yesterday, his spokesman said: "We have no more comment on this apart from to confirm that they are not engaged."
